  •  Probably don't have to manipulate stats (4+ / 0-)

    (I haven't read the thesis).  But if you are just measuring standard IQ tests of 2nd generation immigrants vs. natives, then language difficulties will be more than enough to skew the statistics.  
    You also need to correct for poverty skew (i.e. hungry children do more poorly on tests because they're...HUNGRY) and such.  It's possible to do that, the committee should have asked about it (not that I bothered to check if he did).

    I graduated in the hard sciences.  Thesis there tended to be more binary, i.e. "does the code do what you said it does."

    •  No data can predict IQ scores for two generations (3+ / 0-)

      down the road.  That's pseudo-science at best and racism at worst.  Or both.

      You have exactly 10 seconds to change that look of disgusting pity into one of enormous respect!

        I meant that current testing of 2nd gen immigrants is going to show them at lower IQ scores would show them lower due to language difficulties and poverty skew.

        Actually, once you think about it, you should expect IQ scores to rise dramatically from generation to generation as they become more and more integrated into society (both in terms of language, and 'tests in the US').

    •  It's more than being just hungry. (1+ / 0-)

      A diet deficient in essential protein (amino acids) in young children interferes with brain growth and development.  That deficiency and the damage done is not reversible or curable.  A few years of hunger can seal an individual's future for the worst
